The dispersing solution may also contain copper ions, and the metalcoated particles may be subsequently oxidized or further reduced to modify magnetic properties. The core material may itself be a magnetic alloy, oxide or ferrite (many specified), a non- magnetic oxide, clay or mineral including glass fibre and asbestos. The particles may be acicular, granular or amorphous. In Examples, particles of Fe 2 O 3 , Fe 3 O 4 , FeOOH, kaolin, Al 2 O 3 , cobalt ferrite Mn-Bi, or Fe-Co-Ni alloy are coated with cobalt, nickel, Co-Ni alloy or Co-Ni- Cu alloy. In Example 14 Co-coated Fe 2 O 3  particles are further reduced to produce Co-Fe alloy particles. In Example 18 co-precipitated Co and Fe oxalates are reduced to form Fe-Co alloy particles, which are then coated with Co according to the inventions, and further reduced to form Fe-Co alloy of modified properties.

Abstract: 1399867 Cleaning with non-aqueous solvents IMPERIAL CHEMICAL INDUSTRIES LTD 7 Sept 1972 [27 Sept 1971] 44876/71 Heading D1P Printed circuits comprising lines of flux on resin-bonded paper boards are cleaned by immersion in a heated azeotrope-forming mixture comprising a halogenated hydrocarbon solvent and an auxiliary solvent, the concentration of the auxiliary solvent, being greater than that of the azeotrope, and then rinsed in a second mixture in which the proportion of the auxiliary solvent is lower than in the first mixture. In one embodiment the rinsing mixture is also heated and the two mixtures have a common vapour zone from which the azeotrope is condensed and directed to the rinsing mixture which overflows into the first mixture, a plurality of rinsing mixtures may be employed. Alternatively rinsing may occur in the vapour zone and the printed circuit may be withdrawn from the apparatus and allowed to cool before being rinsed by the vapour. In a modified apparatus the two mixtures have separate vapour zones, condensed liquid from both zones being returned to the second mixture.  Preferred halogenated hydrocarbons are those containing 2 or 3 carbon atoms, especially 1, 1, 2-trichloro-1, 2, 2, trifluoroethane and 1, 1, 2, 2-tetrachloro-1, 2-difluoroethane. Preferred auxiliary solvents are methyl, ethyl isopropyl and tert-butyl alcohol, methyl acetate and nitromethane. The first mixture contains 5 to 63 parts by weight of the auxiliary solvent per 100 parts of mixture in excess of the azeotropic proportion. The concentration of the auxiliary solvent in the rinsing mixture is from that of the azeotrope to 11 % by weight above that. The mixtures may be boiling. Lost solvent is replaced by adding a mixture of the halogenated hydrocarbon solvent and the auxiliary solvent (or the two components separately) in proportions ranging from that of the azeotrope to that of the second mixture.

Title: Nuclear Fuel Element Assembly
IPC: G21C1/08
Filed: 1966-10-11
Abstract: 1,157,907. Fuel elements. COMBUSTION ENG. Inc. 11 Oct., 1966 [2 Dec., 1965], No. 45490/66. Heading G6C. A nuclear fuel element assembly comprises a plurality of longitudinal parallel fuel elements and at least one longitudinal guide rod parallel and coextensive with the fuel elements, the fuel elements being disposed within a predetermined cross-section, a longitudinally extending portion of each guide rod extending outside this cross-section at least partially throughout its length, the longitudinally extending outside surface of each guide rod serving as a guide surface for engagement with adjacent control elements. Intermediate the ends of the fuel elements, fuel element spacing and support means is provided and in the embodiment described (Fig. 5) this comprises a frame 56 defining said cross-section and within which are a plurality of intersecting members 58 which form a grid-like structure. Each member 58 is bent at points 63, which bends extend outwardly from one grid compartment 62 and into the adjacent compartment to form fuel clement engaging arches. Formed from the members 58 are spring tabs 64 which extend into the compartments 62 from two adjacent sides. These spring tabs engage the fuel elements 24 and force them against the opposing arches. The frame 56 is attached to the guide rods 46 as by welding. The fuel elements 24 are rigidly affixed to a bottom support plate, the upper end caps of the fuel elements being a sliding fit in holes in a top support plate. The guide rods 46 are secured to the support plates and serve to tie the entire fuel element assembly together. A cruciform-shaped member affixed to the top support plate facilitates handling of the assembly and assists in maintaining it in the correct position in the reactor core. The prevention of contact between the control rods and the fuel elements as well as the prevention of control rod jamming is accomplished by the guide rods 46 which are of larger diameter than the fuel elements 24 and project through gaps in the frame 56 to form control rod guide surfaces 68. Alternatively (Fig. 13, not shown), a guide rod (82) which is somewhat semicircular in cross-section has a protruding portion (84) which extends through a gap in the frame (56) to form the guide surface (68). Instead of a solid rod, a tube (86), (Fig. 14, not shown) containing a fuel or a poison may be used. A bar (88) attached throughout its length by welding to the exterior surface of the tube (86) provides the guide (68). The guide rods serve to protect the fuel elements from damage during the handling of the fuel element assemblies. The main purpose of the guide rods is, however, to enable the control rod channels to be reduced in size such that the fuel elements on either side of the channel are not substantially farther apart than those within each of the fuel element assemblies, with the resultant elimination of local flux peaking. In the case of a water cooled-water moderated reactor, this eliminates the need for control rod followers.
